Sidewall Installation with
Stationary Glass Facing Outside
CAUTION: Unit must be installed with station-
ary glass facing outside. (Control housing will be
located on the left side of the unit when facing the
unit from inside the house.)
Failure to do so will result in a major reconstruction
and CFM Corporation will not be responsible for
costs associated with incorrect installation..
STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 19)
For combustible walls first frame in opening.
Combustible Walls: Cut a 16¹⁄₄”H x 16¹⁄₄” W (413 x 413
mm) hole through the exterior wall and frame as shown.
Noncombustible Walls: Hole opening must be 11¹⁄₄”
(286mm) in diameter.
STEP 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12”/305 mm). As-
semble sleeve using #8 sheet metal screws (supplied).
(Fig. 20) Install firestop assembly. (Fig. 35)
Zero clearance sleeve is only required for
combustible walls.
STEP 3
Slide the zero clearance sleeve through the wall and
install the firestop on the inside surface of the wall.
Secure with four (4) #8 sheet metal screws.
STEP 4
Place fireplace into position. (Fig. 21) Measure the ver-
tical height (X) required from the base of the flue collars
to the center of the wall opening. NOTE: If using the
SK8DVSK Kit, the vertical section of pipe is telescopic
and could provide adjustment from 24” up to 40” (610 to
1016). Through the wall section shipped with the starter
kit will not be used when going through the wall.
STEP 5
Tape the inner and outer flue collars of the fireplace
using UL approved metal adhesive tape to ensure the
joints are sealed. Attach an appropriate length of vent
pipe to the fireplace. Follow with the installation of the
inner and outer elbow, tape elbow joints and secure
joints as described on Page 17.
